My mother in law got this jumping bouncy house for my kids for Christmas and they LOVE it. It is inflatable...so it is soft if he falls down. It is about 4 feet tall, by 5 feet wide, and is very cute! She bought it on etoys.com. It is only $24.99. Here is a link...maybe this will distract him, and you wont have to worry about him getting hurt! My son is 2 (sept) and they love to jump off furniture, tables, beds, you name it. I think it is definately more of a boy thing than a girl thing. My daughter who is almost 4, is starting it now because she sees her brother. At 2 she never did that! Crazy kids!! :) Good luck...if you have any other questions, let me know :)
